Study the table above: What is the marginal product of the second worker?

A.

10

B.

20

D.

Correct answer is D

Is the change in output resulting from employing one more unit of a particular input, for instance, an increase in labour.

 

From the table above, when the firm had only 1 unit of labour, the output was 10. When it increased its labour to 2, the output increased to 28.

 

Therefore, marginal product of the second worker = 28 - 10 = 18
